You WILL need the MIL eliminators. You don't need to pull the codes unless you really want to. Just install the MIL's and disconnect the battery a while to reset the computer to erase the codes. If the CEL comes back on later then pull the codes and see what it is because it'll be some thing else than the O2 sensors. You DO need the MIL's though when you get rid of your cats. The reason is the way these new OBDII computers are programed for emissions.

You DO need the H-crossover. Those guys are full of crap! Take some black spray paint, or even a crayon and make a line from front to back down the mid-pipes. Where the exhaust heat burns it off of the pipe is where the crossover pipe should be placed. There will be a spot on each pipe where it'll burn out a spot of the paint or crayon. It's all about the exhaust pulse going down the pipes. The crossover pipe equalizes the pressure between the two pipes. If not, can we say Back Pressure?? You definitely need the H-pipe crossover tube.
